My 8 1/2 week spoo has been with us for one week. He already climbs out of his exercise pen, and when I try to take him for a walk he pulls and darts around and tried to play tug of war with the leash. We have a routine of play/exercise then train for a few minutes. Then he is worn out and sleeps in his crate. I need ideas of how to keep him busy during play/exercise time since going for a walk doesn’t work. His attention span is only a few seconds/minutes and he isn’t very food motivated. He also turns into a demon dog if I overtire him. We are frustrated and I am wondering if I am going to be any good at raising a puppy.
